FIELD: instrumentation.
SUBSTANCE: frequency deviation meter includes an intermediate frequency amplifier, a limiter, a delay line, the first envelope detector, a reversible counter, the first circuit containing the first threshold element, a short pulse generator, a convolver, the second envelope detector, the second threshold element, the second circuit containing the first inverter, an “AND” element and the second inverter. The above said elements are connected to each other in a certain manner.
EFFECT: improving measurement accuracy of frequency deviation in a wide range of changes of envelope durations.
